Description
Technical field
The utility model relates to the extensible member that a kind of Self-walking tunneller for tunnel pipeline increases resistance body, belongs to non-excavating underground pipe line laying construction field.
Background technology
Current widely used no-excavation construction method, such as shield method and pipe jacking method, exposed some limitations and not enough, such as advance the problems such as the restriction of length and turning flexibility, these limitations make Urban Buried Pipeline Network construction and underground space development difficult all the more.The appearance of self-travel type tunneling technique and corresponding heading equipment, just overcomes these difficulties.
Self-travel type development machine is utilize the multi-turn being arranged on development machine exterior circumferential to increase stop block soil body stretching embedding in the soil body towards periphery from the principle of walking.The interaction result that multi-turn increases stop block and the soil body provides the axial counter-force needed for body forward thrust, become a kind of completely newly be different from current push pipe and Shield Construction Technique can in soil space urgency curve self-travel type tunneling technique.But still automatically do not prop up and the theoretical research bounced back and practical result about resistance-enhancing component both at home and abroad at present.
Summary of the invention
The purpose of this utility model is to provide a kind of Self-walking tunneller for tunnel pipeline to increase the extensible member of resistance body, it can realize increasing automatically propping up and retraction of stop block, especially its automatic retracted function compensate in current self-travel type development machine advance process increase that stop block embeds after the soil body cannot the deficiency of automatic retracted, and then avoid the disturbance again to the soil body in tunneling process.
For achieving the above object, the technical scheme that the utility model adopts is the extensible member that Self-walking tunneller for tunnel pipeline increases resistance body, and these parts comprise increasing in stop block retraction air bag 1, increasing stop block supporting air sac 2, increasing stop block 3, high-strength bolt 4, W shape structure 5, cylindrical shell stretches the edge of a wing 6; Described increasing stop block 3 is arranged in W shape structure 5, and increasing stop block 3 can slide along the inwall of W shape structure 5; Increase stop block 3 and form upper and lower two chambers with assembling place of W shape structure 5, the lower chambers increased bottom stop block 3 and W shape structure 5 is provided with and increases stop block supporting air sac 2; Increase stop block 3 and the upper chamber at W shape structure 5 top to be provided with and to increase stop block and to bounce back air bag 1; W shape structure 5 is connected in cylindrical shell by high-strength bolt 4 stretches on the edge of a wing 6.
Described increasing stop block 3 radially slides along W shape structure 5 inwall and cylindrical shell.
The amount of movement of described increasing stop block retraction air bag 1, increasing stop block supporting air sac 2 is determined by W shape structure 5.
Automatically propping up with the step that bounces back of this resistance-enhancing component is as follows:
When needing increasing stop block 3 to prop up, first open the relief valve increasing stop block retraction air bag 1, then open the pressurizing valve of increasing stop block supporting air sac 3.
Need to increase stop block 3 when shrinking, first open the relief valve increasing stop block supporting air sac 2, then open the pressurizing valve increasing stop block retraction air bag 1.
Compared with prior art, advantage of the present utility model is as follows:
1, this utility model manufacture craft is simple, apply easier, the again disturbance of development machine to cylindrical shell surrounding soil when walking in soil can be avoided, coordinate and realize unexistent curve turning function in trenchless technology now in great demand, thus bring significant economic and social benefit for tunnel pipe-line construction;
2, rely on pneumatic shuttle to realize increasing automatically propping up and retraction function of stop block, make construction method have the advantages such as convenient, efficient, construction brings safety, also provides strong support and guarantee for applying of self-travel type driving technology simultaneously.

Detailed description of the invention
As Figure 1-4, the utility model is further illustrated.
The present embodiment arranges 3 joint cylindrical shells with development machine, and prosthomere cylindrical shell does not arrange resistance-enhancing component, and middle joint and deutomerite cylindrical shell arrange resistance-enhancing component.Resistance-enhancing component in the present embodiment comprise can move radially along cylindrical shell increasing stop block, ensure to increase the W shape structure propped up restoring device, control to increase stop block amount of movement that stop block moves around along cylindrical shell radial direction, W shape structure is connected by high-strength bolt with cylinder inboard wall, realizes increasing automatically propping up and retraction function of stop block by propping up restoring device.
The preparation method of the present embodiment is as follows:
1, with high-strength bolt 4, resistance-enhancing component is connected in cylindrical shell peripheral annular groove;
2, the relief valve of the increasing stop block retraction air bag 1 be arranged in joint and deutomerite is opened, open the pressurizing valve increasing stop block supporting air sac 2 simultaneously, the increasing stop block 3 be arranged in development machine joint and deutomerite is made to prop up and even embed soil layer with soil layer jam-packed, to the driving mechanism voltage supply connecting prosthomere and middle joint, promote development machine prosthomere and to cut forward the soil body; Removal prosthomere and the middle thrust force saving the driving mechanism be connected, open the pressurizing valve of the increasing stop block retraction air bag 1 be arranged on joint, open the relief valve increasing stop block supporting air sac 2 simultaneously, the contact of the increasing stop block on joint and soil layer is loosened, strengthen prosthomere and the middle pulling force saving the driving mechanism be connected, save the thrust force of the driving mechanism be connected with deutomerite simultaneously in increasing, middle joint is travelled forward; Open the relief valve of the increasing stop block retraction air bag 1 be arranged on joint, the pressurizing valve of open position increasing stop block supporting air sac 2 thereon, make the increasing stop block on joint and soil layer jam-packed, in removal, joint is connected the thrust force of driving mechanism with deutomerite, open the pressurizing valve of the increasing stop block retraction air bag 1 be positioned in deutomerite, the relief valve of open position increasing stop block supporting air sac 2 thereon, increasing stop block in deutomerite is contacted with soil layer loosen, add the pulling force of the hydraulic cylinder group that big-and-middle joint is connected with deutomerite, deutomerite is travelled forward, forms a jacking distance; Repeat above-mentioned steps, development machine is advanced from row cutting in soil layer.
